Forum Features

With the release of YaBB 2.2, and my reinvigoration toward hobby coding, I am curious:

What features would you like to see in a forum?

If you were to install a discussion forum on your own Web site, what features would you want the software to have?

If you were to visit a site that has a forum, what features would you want at your fingertips as a regular user?

What are your thoughts on the matter?
